> The sales representative said that 14.4 can run on the same box as any SMTP > server, but the LISTSERV documentation specifically states this is not true. It's true that LISTSERV needs dedicated port 25 access to one IP address on the server. If you can configure an outbound SMTP server to run on a non-standard port or on a single IP on the server, you can run it on the same server as LISTSERV. (Alternately, you could configure LISTSERV to listen on a non-standard port, assuming your SMTP server knows how to route SMTP mail to that port.) The documentation is correct in the simplest (most common) case, but there are work-arounds for most products. As an example, see the L-Soft whitepaper on configuring LISTSERV and IIS SMTP to run on the same server: http://www.lsoft.com/resources/wp-iis-smtp.pdf We've also been successful in setting up LISTSERV to co-exist with Exchange server by adding a second internal IP address to the server and binding Exchange to the external IP and LISTSERV to the internal one, and then configuring an Exchange connector to route mail to the internal LISTSERV IP via a dedicated FQDN. A bit more complicated, but possible. You could do the same in principle for any SMTP server that can be configured to listen on a single IP address and can route mail to a specific IP based on its FQDN. (This of course requires separate FQDNs for LISTSERV and the Exchange server, although they may point to the same external IP address.) -- Liam Kelly Senior Consulting Analyst L-Soft international [log in to unmask] ------------------------------------- Interested in other L-Soft products?
